Need to clarify the status of Teredo navalis in the Baltic Sea and Greater North Sea; is the species alien or native or cryptogenic (alien status not sure)?

See here: https://www.sciencedirect.com/science/article/pii/S0022098115300587

Whether the occurrence of T. navalis in the Baltic Sea is based on a biological invasion caused by human introduction from somewhere around the world or a purely range expansion starting from an autochthonous European T. navalis population, cannot be clarified with the present data.


Therefore, it should be listed as cryptogenic.
